IodZZ whom. it may concern.-

Be it known that 'I, EUGENE FINQH, of A1- bion, in the county of Orleans and State of New York, have invented certain Improvementsin of which the following is a suitable frame, which is supported on four wheels.

My invention also relates to the combination ofcoltersorcutters with the scoop.

In theaccompanying drawings, Figure 1 is a side elevation. Fig. 2 is a longitudinal see- Fig. 3 is top .view. A is' the frame of the machine, which is sup- .ported on the wheels BB B B.

C is the'scoop, of iron or any suitable material, which" is pivotedat a a, and is raised and lowered by meansof the lever b. a dare colters or cutters attached to the sides of the scoop O, which project beyond the bottom. a

D is an endless apron passing around the rollers d d, and is provided with the ribs or slats e e e, 8m.

E is a shaker,.wh ich consists of a frame prowith bars f f f, &c., sliding freely in the ways 9 9 y- %B is a shaft running across the frame A, which is bent to form a crank at h, and is provided with the pinion G and pulley H.

I is a connecting-rod, which connects the crank h with the shaker E.

J is a cog-wheel attached to the rear wheel, which meshes into the pinion G.

K is a pulley on the upper'roller-shaft, which takes its motion from the pulley H through the chain 75. v y 7 L is an adjustable delivery-spout, which swings on the pivot 2,. i

.M is a lever, which is connected-with the spout by means of the rod m.

The operation is as follows: The machine is drawn along a row of-potato-hills, so that the scoop 0 may out under the hills. The earth and potatoes slide onto the endless. apron D, which throws all onto the shakerE, which, being rapidly moved back and forth, shakes out the earth, 'and the potatoes fall out through the spout L to one side or the other, according as it is. adjusted by the lever M I claim as my invention The potato-digger described, consisting of the frame Aon wheels BB, scoop O, with cutters c c and lever 12, apron D, shaker E, shaft F, with pinion G, pulley H, connecting-rod I, cog-wheel J pulley K, and. adjustable drilling-spout- L, when the parts are arranged as described, for the purpose set forth.
